This invention relates to rolls for wiping down the labels afterthey are pasted on bottles and similar articles.l

AThe principal object of the' invention isto provide rolls of such. a character thatthey will wipe down the label and press it into the corners on a paneled bottle or-the ,like in .which'the panel is depressed below the outside surface of the bottle.

placed, 'it is a diiii'cult matter to `wipe down the label by machinery so that its corners will stick to the bottle, this being due to the fact the panel all around it and prevent an ordi- I nary label wiping device from getting' into Y this space.

Other objects and advantages of the invenv tion will appear hereinafter.A

4 In the' use of labeling machines, it has been practically impossible to apply-labels lying in the sunken panelsof Abottles and get them pastedy down around their edges.

e which projects outwardly around prevents an ordinary label wiping device from enteringlthe panel and particularly en aging the la The ri For` the purposeof'overcoming this ldif- .aficulty,`-I have provided an improved form ofV wiping rolls, and I have shown themas applied to an ordinary labeling machine.

In the case of a panel in which a label is el and pressing it down This involves a table`10, a turret 11 forreceiv- `ing the bottles from the table after theyare labeled in the ordinary way, preliminarily wiped down, and discharging them on a conveyor 12. The details of these features will not be described further, because they are well known, and this invention can be applied to labeling machines of various types, and to the .labeling of'flat surfaces.

While passing from the turret on the 'endless conveyor 12 the bottles a Ae moved through aseries of extra wiping rolls'. Each one of these rolls is formed with awood center 13 on a" vertical shaft 22. On this metal center is a ring 14 of soft sponge rubber, preferably all in one piece. This sponge rubber is of a very yielding character andalso quite durable. On account of the fact that 1t yields so readily it will bear on thelabel withoutmuch.

pressure, but enough to .iforce it down into con.- tact with the bottle at all points.

When the bottle first enters the space between two of these rolls, as shown in Fig. 6,

the spongel rubber yields on both sides, and

yet it comes into the shoulder at the end and edge of each panel and forces the label down against the bottle effectively. The position of the parts when the operation is half completed is shown face of the roll will engage the label in a plane at the bottom of the panel, clear'across,

in cases in which the Abottles are of the ordinary size. Thusthe label is forced against the 'bottle all the way across, clear up into the shoulders, and this pressureis applied for quite a period of time asthe bottle passes through. At the same time this is a comparatively soft and yielding substance and in order to insure a perfect laying down of the edges lof the labels, I prefer to use a lurality of pairs, of these rolls for the bott es to go through one after the other. This will insure perfect action, for if any part of one p'air of rolls does not lengage or force down the label at any ploint eliiciently it will be corrected by one of t e other pairs; '4

As tothe construction and 4operation of these rolls, the matter is taken care of'by a Vradial shaft 16 arranged horizontally and geared to a vertical shaft 17 on the machine.

in Fig. 7 and there the-surwith a` fixed bevel keyed bevel gear 21 which drive two vertical shafts 22 on which the centers of the rolls 13 are fixed. This arrangement is made for the.,

purpose of permitting adjustment for bottles of different thicknesses. The, endless conveyor 12 passes over a horizontal table 24 and a plate 25 is held in horizontal position thereby. The plate 25 is provided with ways 26 in which fit brackets 27 to slide back and forth. These brackets carry the bearings of the shafts 22 and they are held in adjusted position by bolts 28.

In view of this construction it will be seen that one of the rolls 13 can be moved toward and from the other, and is fastened in adjusted position to provide for variations in thickness of the bottles. The shaft 19 is provided with sprocket wheels 29, and there is one of these shafts 19 for each of the pairs of rolls 13. A chain 30 engaging all these sprocket wheels on one side drives them all a ike from the shaft 18.

From this it will be seen that the surfaces of these rubber rolls are so soft that they will accomplish'the pasting down of the labels in the panels most eiiiciently, and that they can be adjusted to anydesired degree of lineness to bear with the proper pressure on the labels,

in accordance with the thickness-of the bottles. Therefore, bythis sim le attachment, bottles of this character can e labeled with the assurance that the edges of the labels both posite sides of the conveyor for extending into said panels on opposite sides of the articles and pressing the labels down throughout their areas, means for driving said rolls, and means vby which one of said rolls can be adjusted toward and from the other for taking care of articles of different thicknesses.

.In testimony whereof I have hereunto affixed my signature.

along the sides and the tops and bottoms will Y lie down smoothly on the glass and adhere' thereto. l

Although I have illustrated and described only a single form of the invention I am aware of the fact that changes can be made therein by any person skilled in the art without departing from the scope of the invention as expressed'in the claims and the invention is useful in wiping down labels on at or concave surfaces on bottles and the like.

Therefore, I do not wish to be limited to the exact form shown,\but what I do claim is:

` 1. The combination with a machine for applying labels in the panels of paneled objects, of a conveyor com rising a horizontal strand for supporting an conveying the labeled articles, a pair of rolls on vertical axes located on opposite .sides of said strand and above it having thick surfaces of sponge -rubber for' yieldingly pressing they labels down within the panels throughout the area thereof, and means for positively driving said rolls from the labeling machine.

2. The combination with a conveyor for vreceiving and taking off articles having labels applied thereto in panels on their surfaces, of ai pair of sponge rubber rolls on op-
